Weight gain showing incorrectly in the app

[Mightypog]

I've looked around message boards quite a bit this morning and remain stumped. On my FitBit app there is a weekly summary of my activity and statistics. Among those statistics is one that shows weight gained or lost. It shows that for each of the last two weeks I gained .1 pounds. I have not been tracking my weight, nor have I been tracking food, nor do I use any other weight or food trackers, nor do I ever weigh myself, so this figure is not coming from any other places. I see that it estimates I have been burning 1997 calories er day. Is it operating on the assumption that I eat a certain number of calories per day? What metrics does it use to estimate weight gained or lost?

Welcome to the Fitbit Community, @Mightypog.

I appreciate your participation in the Forums and sharing that the Fitbit app is showing that you gained .1 pounds for each of the last two weeks. I understand your concern since you're not tracking your weight nor food, I am here to help. Thanks for the details shared, I would like to confirm that the Fitbit app records your weight if you weigh-in with a Fitbit scale, or manually log weight. For more information, see How do I track my weight in the Fitbit app? For information how your Fitbit device calculate your daily activity, see How does my Fitbit device calculate my daily activity?

I recommend trying the following:

1. Log out from the Fitbit app.
2. Force quit the Fitbit app.
3. Reboot your phone.
4. Open the Fitbit app and log back in to your account.

If the issue persists, please let me know if you see the same weight gain on fitbit.com dashboard or in your weekly report email? I will be glad to investigate further. 

Looking forward to hearing back from you.
